SLIDING DOOR.

SPECIFICATION forming part of Letters Patent No. 707,637, dated August-26, 1902.

Application filed October 14, 1901. Serial No. 78,563. (No model.)

To all whom 71mg/ concern:

Be it known that we, GEORGE A. PEOOTOE and EDWIN F. CAREENTER, citizens of the United States, residing at Janesville, in the county of Rock and State of Wisconsin, have invented certain new and useful Improvements in Sliding Doors; and We do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use `Vthe same.

This invention relates to doors and hangers, and particularly to that class known as sliding doors.

The objectof the invention is to provide a hanger and in combination therewith a novel track, whereby the door is frictionally held against accidental displacement when in a closed or open position.

Furthermore, the object of the invention is to provide means for preventing dislodgment of the hangers from their tracks or guides, thereby preventing accidental removal of the door.

Furthermore, the object of the invention is to produce a hanger'for sliding doors" which comprises few inexpensive parts of durable construction, easily operated or controlled, and proving efficient and satisfactory in use.

With the above and other objects in ViewA the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more f ully set forth and claimed. i

In describing the invention in detail reference will be had to the accompanying drawings, forming part of this specication,wl1ere in like characters denote correspondingparts in the several views, and in which- Figure 1 is a view in perspective of a doorframe and the tracks embodying the invention. Fig. 2 is an end elevation of the door and hangers, with the upper and lower tracks or guides in section. Fig. 3 is a plan view of the upper track, partly in section. Fig. 4 is a plan View of the lower door-support. Fig. 5 is a partial end elevation of the door and V.the dislodgment of the door.

In these drawings, 1 indicates ,the doorfrarne, which may be formed in a car-body or in`any building where a sliding door is employed.

2 is a Stringer forming part of the doorframe, to which is securedaJ track 3, which is L-shaped in cross-section. The inner edge of the track is provided with a'seres of thickcned portions 5, 'tapering to the plane of the edge 4, thereby producing cam-surfaces over which the hangers 6 must ride and by which said hangers are directed toward or allowed to recede from the side of the structure which the door is to guard. The purpose of forcing the door toward the structure is to cause its engagement with said structure, frictionally retaining the door in the position placed by the operation against opening by collision, jerks, or other disturbing influences. As soon as the thickened portions are passed by the hangers when traveling in either direction freer movement'is accorded the door, thereby reducing the power required for its movement. Thelower guides or tracks are in the form of an inverted L, While the hangers above are in the shape of an inverted L and the lower hangers are L-shaped, so that the tracks and hangers interlock to prevent It will be noted that these hangers and tracks are applicable to all sliding doors for oars, barns, and in other connections.` Hence it must be understood that various changes may be resorted to in the proportions and details of construction for successfully carrying the device into practice without departing from the scope of the invention.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is i* l. In a sliding door, a fra-me, L-shape hangers, tracks interlockingly connected therewith, a iiange on the upper track projecting from the bearing-face, said flange having enlargements tapered from each end toward the center and an intermediate enlargement op- ISO positely tapered to the surface of the tracks, l form earn-surfaces which force the door insaid tapered portions forming cams for mov- Wardiy, as and for the purpose described. ing the door into engagement with the side In testimony whereof We affix our signaof a car or into its frame, as and for the purtures in presence of two Witnesses.
